CARRIAGE-CURTAIN FASTENER.

SPEGIFICATEON forming `part of Letters Patent N o. 743,903, dated November 10, 1903.

Application filed March l2, 1903. Serial No. 147.498. (No model .To all whom it may concern.-

Beit known that I, JOHN H. MARSH, a citizen ofthe United States, residing at Amanda, in the county of Oconto and State of Wisconsin, have invent-'ed new and useful Improvements in Carriage-Curtain Fasteners,of which the following is a specification. This invention relates to carriagecurtain fasteners, the object in view being to provide what may be termed an"elastic or selfadjusting buttonhole or fastener by means of which a curtain may be quickly and easily secured in place and detached without the expenditure of much strength and effort and Without danger of tearing the curtain adjacent to the buttonholes.

Another object of the invention is to so construct and arrange the parts of the fastener that the size of the buttonhole may be increased or diminished and the tension of the elastic or self-adjusting portion thereof regulated and the wear thereon compensated for.

With the above and other objects in View the invention consists in the novel construction, combination, and arrangement of parts as hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a front elevation of the fastener, shown applied to curtain-sections and shown in operashape, and having the edges thereof punched v to form triangular-shaped Y inwardly-extending prongs 2, which in practice are inserted through that portion of the curtain to which the fastener is applied and clenched upon the opposite side thereof, so as to retain the plate 1 securely in position. V

3 designates a curtain-section, to which the fastener is applied in Figs. 1 and 2, and 4 designates a superimposed section of the curtain,

the saine being shown connected at iis loweredge to one of the bows 5 of the carriage-top frame, said bow being provided at suitable points with outwardly-projecting headed buttons 6, adapted to he received through the buttonholes of the fastener, as illustrated in Figs. 1 and 2.

The plate 1 is provided near one end with a buttonhole, adapted to tit over the headed stud or button 6 in thel manner shown in Fig. 2. The plate 1 is also provided witha threaded opening 8, adapted to receive a clampingscrew 9, which passes through the center of a U-shaped clamp or yoke 10, provided With laterally'and inwardly extending arms or portions 11, the extremities of which are bent to form stop-lips 12, the arms or portions 11 passing through openings 13 in the plate 1, and the stop-lips 12 lying upon the opposite or rear side of said plate and serving to prevent the outward displacement of the clamp or yoke 10, as clearly illustrated in Fig. 4.

14 designates an adjustable spiral springloop, the same being, preferably, endless, as shown in Fig. 1. The spring-loop lies against the outer face of the plate 1 and at one end encircles the buttonhole 7, so as to pass around the shank of the button 6 in the manner shown in Figs. 1 and 2 and`eXerta yielding pressure thereon, which will prevent the accidental unbuttoning of the curtain and at the same time permit the said curtain to be unbuttoned when sufficient force is applied thereto in the proper direction. Opposite portions of the spring-loop pass through and beneath the clamp or yoke 10 and on opposite sides of the centrally-arranged clampingscrew 9, as best illustrated in Fig.` 4, the said side portions of the loop being held and clamped between the outer portion of the clamp or yoke and the outer surface of the plate l.

In adjusting the spring-loop 14 the pressure of the clamp 10 is relieved by loosening the screw 9. This allows the spring-loop to be adjusted so as to fit with the necessary tension around the button 6. When the proper adjustment has been obtained, the clamp is tightened, thus preventing anyslipping of the spring-loop. When properly adjusted, that portion of the spring-loop which encircles the buttonhole and button will ad- IOO just itself and the button and at the same time yield to allow the button to pass through the plate l and the end portion of the springloop, as shown in Figs. l and 2. When the button is in place, the spring.- loop rests against the shank of the button and behind the enlarged head thereof, as shown in Fig. 2, and prevents the curtain from becoming unbuttoned. Whenever, by reason of wear or stretching, the spring-loop becomes enlarged sufficiently to render the fastening device unreliable, said spring-loop may be taken up by means of the clamp or yoke 10, and should that portion of the spring-loop which bears directly against the button become too Vfar worn the' spring-loop may be adjusted through the clamp, so as to bring a new and unused portion of the loop to hear against the button.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

A carriage-curtain fastener provided with a buttonhole, a spiral spring-loop attaehed to the plate and extending around said buttonhole, and means for adjusting the tension of said spring-loop.

2. A carriage-curtain fastener comprising a plate" provided with a buttonhole, an elastio loop extending around the buttonhole, and a clamp connected with the plate adapted to yield and admit of the adjustment of said loop.

A carriage-curtain fastener comprising a plate provided with a buttonhole, a springloop extending around the buttonhole, and a movable clamp for holding and adjusting said loop, said'elamp having its opposite portion extended through openings in the plate and provided with stop-lips, substantially as and for the purpose described.

4. A carriage-curtain fastener comprising a plate provided with a buttonhole, a clamp or yoke having arms extending through openings in the plate and provided with terminal lips, and a clamping-screw passing centrally through the clamp or yoke and engaging said plate, opposite portions of the loop being extended through the clamp on opposite sides of the clam ping-serew and adapted to be held between the clamp and plate, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
